No one can figure out the ‘whole Work of God’.
None is able as it is written:
“When I gave my heart to know wisdom and to see the task which has been done on the earth (even though one should never sleep day or night),
and I saw every work of God, I concluded that man cannot discover the work which has been done under the sun. Even though man should seek laboriously, he will not discover; and though the wise man should say, “I know,” he cannot discover.” (Ecclesiastes 8:16 -17)
But He intends Good only:
“He hath made every thing beautiful in His time: also He hath set the age in their hearts, so that no man can find out the work that God maketh from the beginning to the end.” (Ecclesiastes 3:11)
It is so ‘hidden’ that even translators have ‘great trouble’ translating such verses ‘correctly & literally’ which further prove these verses true.
